Rest in Peace Tex Logan, Distinguished Member of Bell Labs Technical Staff and World Class Fiddler
Here is a Eulogy I wrote for his memorial service today, April 30, 2015

These are archive course notes for prior classes

Please attend the CRAW Seminar Wednesday March 5 from 2:30 to 4:00 in the Dean's Conference Room
These are current Instrumentation and Measurement activities on the Oregon Coast.

Note: Extra Credit for appropriate questions to Dr. Shearman about his measurement system hardware.
some of Dr. Shearman's other work involves deploying inexpensive temperature sensors on commercial fisherman crab pots

Analog Signal Labs

Dr. Campbell's Analog Signal Labs has three laboratories in off-campus locations.
Each has external antennas and access to signals and natural environments not available at an urban campus.

The primary focus of Analog Signal Labs is the hardware/electronics transition between the natural world
Electromagnetic and Acoustic environments and the input to an Analog to Digital Converter (ADC) for subsequent
Digital Signal Processing (DSP).

The Rad Lab

The Rad Lab is the primary design, fabrication, test, and measurement facility for
new RF and analog signal processing hardware, antennas, and sensor platforms.

Facilities include:

Complete Analog/Acoustic/RF bench

Microelectronics fabrication bench

Machine shop

Antennas from 60 kHz through 10 GHz

Baseband DSP hardware and signal processing software to 24 kHz

EZNEC Antenna design software

RF Power measurement from the thermal limit to 250 Watts

Amplifier distortion measurement from baseband to 10 GHz

Short Range 6 GHz Reconfigurable Modulated Scatterer Radar

Medium Range 6 GHz Reconfigurable Modulated Scatterer Radar

The Loft

The Loft is an actual upstairs loft in a small town residential area geographically and electromagnetically isolated from Portland.
The Loft has HF antennas and easy access to RF quiet environments for field testing hardware, studies of Ionospheric Propagation
and measurements of rural, rural-residential and marine electromagnetic and acoustic noise environments.

The QUIET Lab

The QUIET Lab is a small off-grid RF and Acoustic laboratory on board the Sailing Vessel Lady Day.
Auxiliary power on SV Lady Day is diesel. Electrical power is battery and solar, for near-zero platform noise.
Lady Day may be anchored thousands of meters from shore-based noise sources such as 60 Hz lines, switching power supplies,
and microprocessors, which provides a broadband electromagnetic and acoustic noise floor approaching the thermal limit.
Lady Day and associated small craft provide a convenient platform for field testing undersea acoustics hardware.

Analog Signal Labs Collaborators

Analog Signal Labs is engaged in formal and informal collaborations with the 1/f Noise Lab at Cascade Microtech, the Microwave
Device Characterization Lab at TriQuint Semiconductor, Wireless Remote Sensing lab at Lizard Monitoring, Kanga US, Geesman Violins,
and a steadily growing list of other Portland laboratories engaged in low-noise, high-frequency and on-wafer measurements.
A most delightful and entertaining set of collaborations involves the extended community of recently retired former Bell Labs colleagues,
academic scientists, and Research engineers who invented the technical world as we know it and haven't slowed down a bit now that
they are free to pursue curiosity-driven basic rather than externally-funded applied research.

The Tall Ship extended family is mourning the loss of HMS Bounty at sea yesterday

HMS Bounty was a school ship, an extended community, an iconic bit of history,
and a gathering place for thousands of her students and former crew.
14 of her crew were successfully rescued. Deckhand Claudene Christian did not survive.
The Coast Guard continues to search for her Captain, Robin Walbridge.
